Failure of self-righting frame on Fast Rescue Craft (FRC)

What happened?

During a routine rescue drill the self-righting frame assembly fell off the Fast Rescue Craft (FRC) into the water while the FRC was transiting at approximately 15 knots. The self-righting frame was recovered by the FRC crew and returned to the vessel, where the cause of failure identified, and repairs completed.

What went right

• The hazards and risks of the rescue drill had been identified and discussed in the Toolbox talk with all personnel involved;
• Appropriate protocol was followed, and Bridge crew were kept in communication throughout the recovery operation;
• The FRC was repaired promptly to Original Equipment Manufacturer (OEM) specification.

What went wrong

• A third-party inspection of the FRC had been completed two months before the incident. The inspection required only a visual check of the self-righting frame and did not include checking the integrity of the frame securing arrangements;
• Over time the securing arrangements were stressed and showed signs of galvanic corrosion.

What lessons were learnt?

• The integrity of self-righting frames should be periodically inspected. This may involve the removal of the frame;
• Reviewed FRC inspection checklist and procedure to ensure the self-righting frame is periodically removed and inspected.
